ASAP HELP The equation for QR is 5y = -40 +41. Is QR tangent to Circle O at R?
YA
No, because the slope of OR times the slope of QR
does not equal 1.
R(4,5)
Yes, because the slope of OR times the slope of QR
equals 1.
No, because the slope of OR times the slope of QR
does not equal -1.
Yes, because the slope of OR times the slope of QR
equals - 1.
